# Prerequisites for Edge Spoke Gateway Deployment on Aviatrix Edge Platform
> The following are the prerequisites to deploy an Aviatrix Edge Spoke Gateway on the Aviatrix Edge Platform.
The following are the prerequisites to deploy an Aviatrix Edge Spoke Gateway on
the Aviatrix Edge Platform.
## 1. Procure and Onboard the Edge Device
Before you can deploy an Aviatrix Edge Spoke Gateway, you must procure and
onboard your edge device onto the Aviatrix Edge Platform. For more information,
see
Installing Edge OS and Onboarding Dell Hardware
.
## 2. Obtain Edge Gateway Interface IP Addresses
The Edge Spoke Gateway on the Aviatrix Edge Platform supports one WAN, one LAN,
and one Management interface.
You will need to provide the following information during Edge Gateway creation
for your primary and secondary HA Edge Gateways.
| WAN Interface | Description |
| ------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Interface CIDR | The CIDR for the WAN interface. Interface CIDR must be in the format *interface\_ip/netmask* (for example, 192.18.20.1/24). |
| Default Gateway IP | The Default Gateway IP address for the WAN interface. For CSP underlay, this is the remote side IP address of the BGP session on CSP VNG or VGW. If Link-Local Underlay CIDR is configured, the Default Gateway IP should be in the same subnet as the Link-Local Underlay CIDR, otherwise, it should be in the same subnet as the WAN Interface CIDR. |
| Public IP | The public IP for the WAN interface. The public IP of the WAN interface is used for peering connections over the public network. |
| LAN Interface | Description |
| -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Interface CIDR | The native VLAN interface IPv4 address. This interface is where untagged packets are sent. |
| IPv6 CIDR | The native VLAN interface IPv6 address. This interface is where untagged packets are sent. |
| VRRP Gateway IP | The Virtual IP for the VRRP Gateway, when VRRP is enabled. |
| Default Gateway IP | The Default Gateway IPv4 address for the native VLAN interface. |
| Default Gateway IPv6 | The default Gateway IPv6 address for the LAN interface when Support for IPv6 is enabled. Not required if not using Virtual Router Redundancy Protocol (VRRP). |
| VLAN ID | The VLAN ID of the VLAN segment. VLAN ID must be a number between 2 and 4092. |
| VLAN Interface CIDR | The VLAN IP address of the VLAN segment. |
| Default Gateway IP | The Default Gateway IP address of the VLAN segment. |
| MGMT Interface | Description |
| ----------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| IP Assignment | The MGMT interface defaults to **DHCP**. This setting cannot be changed. The Edge Gateway will automatically NAT out of the physical MGMT interface of the edge node when using the Aviatrix Edge platform. Please see the Known Issue regarding the Management interface IP assignment. |
| Private Network | Leave this setting to **Off**. The Edge Gateway on the edge hardware requires public Internet reachability to connect to the Aviatrix Controller and Aviatrix Edge infrastructure in the cloud. |
| Egress CIDR (Primary) | The Egress CIDR is the public IP address which the Management interface uses. If the Public IP is used from Edge Gateway Management interface to establish connectivity to Aviatrix Controller, then configure the Public IP as the CIDR. The CIDR is then added to the Controller security group to allow incoming traffic from the Edge Gateway. |
| Egress CIDR (Secondary) | The Egress Public IP for the secondary Edge Gateway's Management interface when High Availability is configured. |
## 3. Provide Network Access
Aviatrix Edge Spoke Gateway requires outbound access to communicate with the
Aviatrix Platform. You must allow access on the specified ports on your
firewall.
For all Edge gateway outbound access requirements, see
